Most likely your trailer has a 7-way and the reason you referred to it as a 6-way is because you didn't count the center plug. But either way I can help if you have either a 6 or 7-way.

Since not all trailer connectors will use what is considered the standard wiring setup you would need to check out both of the connector diagrams I attached to determine which wire would be the ground circuit on the connector of your trailer.
